Assessment metrics

In the Assessments application, a metric is a
trait or value used to evaluate assessable records.

Depending on the metric method, a metric can be used as either of
the following:

A question on assessment questionnaires, to obtain a subjective value such as how much
people enjoy using each cell phone offered in the service catalog.

A script that queries the database, to obtain an objective value such as the number of
incidents related to each cell phone.

Each metric is associated to one metric category and can be
used to evaluate assessable records for that category only. For example, the Support Rating
category contains metrics that measure the quality of vendors' customer support services. One
metric addresses the quality of product documentation. Others address the strength of the user
community, self-service options, online training, and other support services. Each metric has a
numeric weight value to indicate its importance relative to other metrics in the same
category.

Assessment administrators can create and administer metrics and metric templates, which
define reusable sets of answer options for metrics used as assessment questions. If you decide to
use metric templates, you may want to create them before you create metrics.

Note: Changes to
assessment metrics and metric templates are reflected in assessment questionnaires and results,
even if users have saved responses already. If possible, avoid changing the original meaning of
a metric question, the data type, or any metric templates in use by existing
assessments.
